以水为提取剂,对棘托竹荪子实体进行浸提,利用琼脂甲板打孔法测定棘托竹荪子实体对大肠杆菌O157:H7、副溶血弧菌、单增李斯特菌、肠炎沙门氏菌和金黄色葡萄球菌的抑菌效果,并研究其对5种病原菌的最低抑菌浓度(MIC)、热稳定性以及抑菌pH值范围.结果表明,棘托竹荪子实体的浸提液对副溶血弧菌抑制作用最好,其次是单增李斯特菌、大肠杆菌O157,对肠炎沙门氏菌、金黄色葡萄球菌抑制效果最差;棘托竹荪子实体的浸提液最低抑菌浓度小,抑菌pH值范围广而且热稳定性强.

Aqueous extract of Dictyophora echinovolvata fruitbody was prepared by boiling water extraction and its antibacterial activity against 5 species of common food-borne pathogenic bacteria was investigated by agar diffusion plate method. Additionally, the minimum inhibitory concentration (MIC) and thermal stabifity as well as antibacterial pH range of this extract were also analyzed. The extract of Dictyophora echinovolvata fruithody displayed the highest inhibitory effect against Vibrio parahaemolyticus, followed by Listeria monocytogenes and Escherichia coli O157:H7 while no significant bacteriostatic effects were observed on Salmonella enteritidis and Staphylococcus aureus. Tiffs extract possessed quite lower MIC values, wide antibacterial pH range and the strong thermal stability.
